A Comanchero bikie boss who was arrested in raids across Sydney last week has been formally refused bail.

More than 100 police raided ten properties across Sydney a week ago.

Eight members of the Comancheros were arrested at the gang's Milperra clubhouse including Comanchero boss Giacomo 'Jack' Dipizio.

The 34-year-old has been charged with trying to blow up a hotel in the suburb last year, the same site as the infamous Milperra massacre in 1984 involving the Comancheros and rival gang the Bandidos.

Dipizio did not appear in Sydney's Central local court this morning and there was no application for bail.

The case has been adjourned until July.

An airport baggage handler caught up in last week's bikie raids has also been refused bail.

Tyrone Nastevski was arrested at the international terminal of Sydney Airport.

The 23-year-old has been charged with supplying drugs.

He will appear in court next month.
